Ted S posted:I love the design! Does your software have the ability to create a 3D rendering, to illustrate the vertical separation between mainlines? The only true "over & under" is the NS interchange on the right side, correct? And you're gaining 7" of vertical separation in about 20 feet, right?
Thanks so much for sharing your excellent design and thought process. Pretty soon we'll look forward to seeing pictures of the real thing!!
Thank you Ted! AnyRail does a 3D rendering, but its not really that good, so I rarely use it, but sometimes. The only real grade is as you observe, on the BNSF climing at the top and over the right side and across the long bridge to Cascade.
The grade climbs 9" in 24 feet (about 3%, the precise 3% would be 9" over 25'). I use the approximation of Woodland Scenics inclines, which is based on inches climbed in 8', or 96", which is close to 100 inches. So Woodland Scenics is off a bit on the math, but then easier to use based on 8', 4', 2' etc, much more convenient and practical.
